-Focus on the reduced role of viability testing in the setting of STICH trial viability substudy. Possible hypotheses for the failure of viability testing.
-Global revascularization is best performed regardless of viability testing.
-Viability testing may have a role in guiding regional revascularization, particularly when PCI is chosen
-Viability testing may have a role when single vessel CTO PCI is considered for HF purposes.
-Role of Q waves
